дома Фармацевтический Лактоза Lactose Monohydrate
Product Name: Natural Crysta Lactose Monohydrate
Chemical Name: Lactose Monohydrate
CAS No.: 5989-81-1
MF:C12H22O11.H2O
Appearance: Crystal powder
Description:
Lactose Monohydrate is a unique, excellent tasting sugar-free bulk sweetener. Because the same amount of Lactose Monohydrate is used in products as would be used if they were sweetened with sugar, Lactose Monohydrate-containing products have the same appearance and texture as those made with sugar.
Discovered in the 1960s, Lactose Monohydrate is made from sucrose and looks much like table sugar. It is white, crystalline and odorless. Lactose Monohydrate is a mixture of two disaccharide alcohols: gluco-mannitol and gluco-sorbitol.
Application:
Powder mixing, capsule / granule filling, pellet core, dry powder inhalation, wet granulation, premixing.
Specification:
Items |
Standard |
Identification A |
The infrared absorption spectrum of the sample is concordant with that of the standard. |
Identification B |
The principal spot obtained from the Test solution corresponds in appearance and RF value to that obtained from Standard solution A. |
The test is not valid unless the chromatogram obtained with Standard solution B shows four clearly discernible spots, disregarding any spots at the origin. |
|
Residue on ignition |
